[BUG] MQTT expire_after doesn't work

[Mikescotland]

Describe the bug Adding mqtt expire_after: 120 should reduce sensor.person to 2 minutes. No matter the value, it takes 600 seconds, exactly like without this parameter.

Version of Double Take Latest beta

Expected behavior Mqtt should expire after given time, so the sensor should revert to not_home after given time
